Free, professional dataset annotation tool for editing bounding boxes in images. Supports Pascal VOC XML, YOLO, JSON formats. It lets users load a local folder of images and their XML annotation files (Pascal VOC or custom formats) directly in the browser without uploading anything to a server. Inspect and edit bounding boxes, adjust class labels, delete images, create missing XMLs with configurable mappings, and save changes back to the original files.

Hi Product Hunt, We built this tool after repeatedly struggling with inconsistent bounding-box annotations and the friction of setting up dataset viewers and annotation scripts. Our goal was to make dataset cleaning realistic, visual, and simple — all inside the browser, with no setup required. We’d love feedback from the machine learning community on features that would make dataset QA faster and more intuitive.
